Perpetual Protocol/Tether (PERPUSDT) opened at $0.27 on 2025-09-18 12:00 ET and traded to a high of $0.2743 before closing at $0.2635 at 12:00 ET on 2025-09-19. The 24-hour total volume was 419,507.99, with a notional turnover of $108,565.60. A bearish trend emerged as the pair traded below key moving averages and showed signs of exhaustion.

Structure on the 15-minute chart revealed a strong bearish bias, with a broad consolidation forming after a sharp initial drop from 0.2743 to 0.2632. A bearish engulfing pattern was observed near the high of the session, indicating a rejection of higher prices. A doji near 0.2720 hinted at indecision, but downward momentum quickly resumed. Key support levels appear at 0.2632 (swing low) and 0.2615 (Fibonacci 61.8%), while resistance is seen at 0.2662 (Fibonacci 38.2%) and 0.27 (initial breakout level).

The 20-period and 50-period moving averages on the 15-minute chart both trended downward, with price currently below both. The daily 50-period MA remains above the 200-period, suggesting a longer-term bearish bias, but the 100-period MA is approaching the 200-period from below, indicating potential for a trend continuation. The RSI dipped below 30 for much of the session, signaling oversold conditions, while the MACD remained negative with a flattening histogram, hinting at potential bear fatigue. Bollinger Bands showed moderate expansion, with price resting near the lower band for most of the session, reinforcing the bearish sentiment.

Volume remained strong during the late afternoon and evening ET hours, especially in the 0300–0500 ET window, aligning with the bearish price action. However, as the session progressed, volume and turnover declined, and price failed to retest earlier intraday highs, suggesting a potential lack of follow-through on the bearish thesis. A divergence between price and turnover—where volume fell but price continued lower—was observed in the last 4 hours, adding a layer of caution for near-term longs.

Backtest Hypothesis
The bearish bias on the 15-minute chart supports a short-term bearish trading strategy. A potential backtesting framework could involve entering short positions at the open of a candle breaking below a key Fibonacci support level (e.g., 0.2662) with a stop above the recent swing high (0.2683). A target could be placed at 0.2615, the 61.8% Fibonacci retracement level. Given the RSI reading in oversold territory and the alignment of moving averages, this setup could be tested using a 1:2 risk-to-reward ratio over a 24-hour period. The strategy would aim to capture continuation in a defined trend while avoiding entries in high-volatility consolidation phases.
